Not uncommon. Moderately common in old sand quarry sub- 

 ject to the spray of the sea, Cumbrae. Common in Johnston Loch 

 (June), and Mugdock Loch (October); Antermony Loch (October), 

 very common, but all immature. Dr. Brady says that it is his 

 experience to find this species haunting small grassy pools where 

 the water is considerably impregnated with organic matter.* This 

 appears also to be the case, to some extent, on our side of the 

 border ; yet it is frequently met with in lochs of considerable 

 extent.

Not uncommon in brackish water. Common in a pond on the 

 Hunterston shore, opposite Millport, subject to the spray of the 

 sea. Moderately common in a pond at Ferry House, Cumbrae, 

 now filled up, where the conferva} of the pond were washed up a 

 foot or more by the waves of the sea during a storm at high tides. 

 Yet, after the subsidence of the storm, this species, together with 

 Cypris aculeaia, was found to have kept its place, being still 

 plentiful. This pond was very small, not covering more than two 

 superficial poles, and must have been quite salt when covered by 

 the sea; yet in the dry season of the year, being supplied by a 

 drain, it must have been comparatively fresh. In brackish water, 

 Lewis.

Not uncommon in fresh-water gatherings. Although a Cypris, 

 its true habitat appears to be in the mud at the bottom. A 

 gathering from a clay hole at Portobello, near Edinburgh, sent 

 me by Mr. James Bennie, was crowded with this species. It is 

 also common in Dunsapie Loch, Arthur's Seat, Edinburgh. This
